[meme] Trains are 100000x easier to electrify and automate than cars, so why does everyone keep talking about electric and driverless cars? - eviltoast

    Absolutely. And the benefit trains have over cars is that you can reduce the amount of other stuff per person needed to get people moving.

    For a local train of mine that seats 93 people with empty weight of 54 metric tons, that comes out to ~0.58 tons/person.

    My sedan weighs in at about 1.5 metric tons empty, and since I’m the only one that uses it, my weight footprint is ~1.5 tons/person.

    Forget about fuel economy too. Trains don’t have traffic (most of the time) to deal with, meaning they can accelerate to coasting speeds and spend most of the ride at best-efficiency. Cars are subject to traffic conditions, meaning efficiency can be as-designed by the manufacturer, or it can be much, much worse on a per trip basis if you contribute to the daily rush hours on freeways.

      There is also much less friction on rails compared to rubber on roadways. If demand increases the length of the train can be increased or more trains added. This helps prevent the cycle of needing more lanes (rail lines in this case).
